Uncovering Metal-Decorated TiO Photocatalysts for Ciprofloxacin Degradation-A Combined Experimental and DFT Study.

Optimization of the efficiency of the photocatalytic degradation of organic and pharmaceutical pollutants represents a matter of fundamental and practical interest. The present experimental and DFT study deals with evaluation of OH radical binding energy as a simple computational descriptor of the catalytic activity of metal-decorated TiO photocatalysts for the photodegradation of the widely used antibiotic ciprofloxacin. Five metals commonly used in catalytic materials (Zr, Pt, Pd, Fe, and Cu) were deposited on the TiO surface, and the obtained photocatalysts were characterized experimentally (XRPD, ICP-OES, and SEM) and theoretically (DFT).

Health-related quality of life in different stages of breast cancer in Serbia.

Objective: Breast cancer is the most commonly diagnosed malignant tumor worldwide, and Serbia ranks first in Europe in standardized breast cancer mortality rate. The aim of this research is to estimate health-related quality of life (HRQoL) and work productivity among patients in different stages of breast cancer in Serbia.

Subjects And Methods: A total of 175 breast cancer patients attending the breast cancer outpatient clinic at the Oncology Institute of Vojvodina between March 2022 and February 2023 were included in the study.

Economic burden of breast cancer in northern Serbia.

Introduction: Breast cancer is the most common cancer in terms of incidence and mortality among all cancers in women in Vojvodina, the northern region of Serbia. In addition to the effectiveness and safety of therapy, it is important to put emphasis on the cost of treatment, as well as on the optimal allocation of limited resources.

Objectives: This study aimed to assess the overall economic burden of breast cancer in Vojvodina, as well as the ratio of direct and indirect costs in 2019.

Oil contamination of sediments by freeze-drying versus air-drying for organic geochemical analysis.

Freeze-drying is widely used in geochemical laboratories for preparing wet solid environmental samples such as sediments and soils before being analyzed for their contents and states of various metal elements and labile organic components that may be temperature- and/or redox-sensitive. Screening bulk geochemical analysis of two Artic lake sediment samples prepared by freeze-drying displayed unexpectedly high contents of labile organic matter (OM) represented by the Rock-Eval S1 peaks (e.g.

The Influence of a Binder in a Composite Electrode: The Case Study of Vanadyl Phosphate in Aqueous Electrolyte.

Layered VOPO·2HO is synthesized by the sonochemical method. An X-ray powder diffraction is used to examine the crystal structure, while scanning electron microscopy is used to reveal the morphology of the powder. The crystal structure refinement is performed in the P4/Z space group.
